Display apparatus with decorative lighting unit

Abstract

A disclosed display apparatus is provided including: a rear case having an inner space; an image display unit installed in the inner space of the rear case, and in which an image is displayed on a front surface; and a decorative lighting unit including a light diffuser installed around the image display unit in the inner space of the rear case, and formed with a grid pattern, and a decorative light source arranged behind the light diffuser to transmit light through the light diffuser.

What is claimed is: 
     
       1. A display apparatus comprising:
 a rear case having an inner space; 
 an image display unit installed in the inner space of the rear case, and in which an image is displayed on a front surface; and 
 a decorative lighting unit including a light diffuser installed around the image display unit in the inner space of the rear case, and formed with a grid pattern, and a decorative light source arranged behind the light diffuser to transmit light through the light diffuser; 
 wherein the light diffuser includes an opaque-colored partition wall having a grid-type planar shape to define a plurality of cells arranged to form a matrix, and a plurality of light diffusion blocks formed of a light diffusion material and fitted one by one into the plurality of cells. 
 
     
     
       2. The display apparatus of  claim 1 , further comprising an inner case installed in the inner space of the rear case, and configured to support the image display unit so that the image display unit is located at a central portion of the rear case. 
     
     
       3. The display apparatus of  claim 1 , wherein light incident on a rear surface of one light diffusion block among the plurality of light diffusion blocks is blocked by the partition wall in surface contact with a side surface of the one light diffusion block, and thus is diffused only in the one light diffusion block and emitted to a front surface of the one light diffusion block. 
     
     
       4. The display apparatus of  claim 3 , wherein the decorative light source includes a plurality of light-emitting diode packages arranged behind the plurality of light diffusion blocks in a one-to-one alignment and an LED board on which the plurality of LED packages are mounted. 
     
     
       5. The display apparatus of  claim 4 , further comprising a heat resistant double-sided adhesive tape having one side surface adhered to the LED board and the other side surface adhered to a bottom surface of the rear case to fix the LED board to the rear case. 
     
     
       6. The display apparatus of  claim 1 , wherein the image display unit includes an LCD panel including a pair of substrates spaced apart from each other and a liquid crystal layer interposed between the pair of substrates, and a backlight unit (BLU) configured to project white light onto the LCD panel from behind the LCD panel. 
     
     
       7. The display apparatus of  claim 1 , wherein the decorative light source blinks in synchronization with the image displayed on a front surface of the image display unit.
